Pregnancy Loss (Miscarriage) in Horses



The course of treatment will ultimately depend on the cause of the abortion. For example, if the abortion was caused by infection, the veterinarian will prescribe medication to eliminate said infection. The gestational period in which the abortion occurred in the mare will also be a factor in the type of treatment the animal receives.


Living and Management


A healthy mare is critical to a successful pregnancy and a healthy foal. While you may not have much control over the proper development of the fetus, caring properly for an expecting mare is half the battle. Proper feeding with proper supplementation is always a good idea for a healthy mare and foal.




Mares that are normally less healthy than other horses should not be allowed to become pregnant; likewise with older mares. It may also be a smart idea to keep a pregnant horse away from other horses in the farm during the period of gestation.


You know your horse better than anyone. Pay close attention to their health, their attitude, and their comfort. If you feel any doubt about the quality of their health, seek the advice of your veterinarian as soon as possible.


It is also important to vaccinate against EHV-1, which can cause spontaneous abortion in mares.
